Amazon has quietly upgraded its Kindle Colorsoft Signature Edition for 2025, offering notable enhancements in display and overall performance. This improved version now features a revamped display structure that avoids the previous issue of developing a yellowish bar at the bottom, providing higher color saturation and deeper blacks. Additionally, the device incorporates more recycled materials—an increase from 18% to 29%—reflecting a commitment to sustainability.
In mid-July, Amazon introduced a new 16 GB base model for the Kindle Colorsoft, alongside apparent updates to the Signature Edition. However, identifying the new model can be tricky due to unchanged model numbers on the packaging, as the label “SA59CP” is still in use. This has created some confusion, especially with older models still in circulation.
The 2025 variant is reportedly identifiable by a DSN code containing “H70,” but it remains uncertain if this applies universally across all markets. Major internal upgrades include a new motherboard and processor, which are expected to enhance performance. Furthermore, adjustments to the charging coil improve compatibility with certain Qi charging pads.
These updates make the Kindle Colorsoft Signature Edition a more compelling choice for e-reader enthusiasts seeking improved visuals and eco-friendliness. The subtle but impactful changes continue to position Amazon as a leader in innovative e-reader technology.
